Gold-plated Jewelry vs. Real Gold – Why the Difference is Huge

Gold-plated jewelry has a thin gold surface layer (0.5–5 micrometers) on a non-precious metal core. Real gold (14K, 18K) is precious metal throughout. The difference in durability is fundamental: plating wears off, solid gold does not.

What is gold-plated jewelry?

• Core: Brass, copper, or silver (sterling)
• Surface coating: Gold layer, 0.5–5 micrometers thin
• Inexpensive – because it contains very little gold
• Problem: Layer wears off – especially in areas of friction
• Typical for: Thomas Sabo pieces, Pandora Rose, Pandora Shine, cheap costume jewelry

What is real gold?

• 14K gold: 58.5% pure gold + alloy metals
• 18K gold: 75% pure gold
• No coating – the metal IS gold
• Never discolors, doesn't wear through
• Hallmark guarantees: 585 or 750

Long-term comparison

• Gold-plated after 2 years: Areas with abrasion show base metal; inexpensive to replace or cannot be restored
• Real gold after 20 years: Just as gold-colored as on the first day – with patina, but unchanged in color

FAQ

How do I tell the difference between gold-plated and real gold jewelry?

Hallmark: 585 or 750 = real gold. 925 = silver (even if gold-plated). "GP" (Gold Plated) or no stamp = gold-plated or brass. At Corelune, the fineness is indicated on every piece.
